To all whom t may concern.'

Be it known that we, MAURUs l. Uns- 'rnnIcH and HENRY N. OESTREICH, citizens of the United States, residing at Philadelphia,

in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements 1n Convertible Relectors for Lamps; and we do hereby deerly illuminate' a road when traveling thereover constitutes a serious inconvenience when two vehicles attempt to pass eachl other in thatthe glare blinds the driversso that they cannot see the other vehicle. Also, tin cities the use of a glaring head light is generally prohibited. 4

It is therefore the object of the invention to provide means associated with high power, lamps of automobiles or other ve hicles vwhereby the amount of light given n out by lamps may be reduced as desired,

and it is more specically the object to accomplish this by providing means whereby the reflectors of the lamps may be covered by shield' portions having. relatively low power of reflection.4

It isfurther an object to provide such meansfor 4dimming' the lights of lamps wherein electricity supplies the light.

With the above and other objects and advantages in view, the invention resides more particularlyr in the novel combination,

-formation and arrangement of parts as more A fully Qdescrihed hereinafter and pointed out' in the appended claims.

Reference is had to the accompanying drawings, whereinl similar characters of reference designate corresponding parts throughout the several `views5 and in which:

vertical sectional view ltl'irolrgh the struc` turen shown in Fig. l. Fig. 3 is a transverse sectional view. Fig. 4- is a side elevation ofthe redentor dimming shield removed. A

Referring now more particularly to the accompanying drawings there is shown an electric headv light of the ty e generaily used on automobiles and inclucing the cup shaped lamp casing 5 carrying at its mouth theA usual lamp ring 6 and adapted to be supported as by the usual bracket 7. rl`he base of this casing .is provided with a. bearing portion 8.

The reflector :for the lamp comprises a cup-sliaped member Q which'seats in the cas ing and. is held thereto by a lateral flange l0 at its mouth. The shield member 1l :for

coveringthe refiector to dim the light is' also cup-shaped' to seatwithin the reflector portion and is provided at its mouthwithf a iiangel'slidably resting against the re- Hector flange l0. The base of the shield member carries a sleeve 3.3 which extends through an opening 14 inthe base ofthe reflector and through the bearing 8 of the lamp casing. rl`his sleeve carries the lamp proper l5 and the-*wires with current and the sleevei'extends outwardly of the bearing 8 andcarries a lat-` eral arm 17 whereby the shield may be rotated.

1 6 which supply` it i The Shield is provided with nots is extending radially from apoint adjacent its base to a point adjacent its mouth portion and the ends of these slots are extended laterally at l) concentric to the axis of the shield to form tongues 20, the shield being similarly disposed with relation to the slots"w 18 and having their ends laterally dinected-` at Q2 in a similar manner, `and the tongues divided. into quadrants by lthese slots. The

reflector member 9 is provided with slotsfl ,5?*5i 20`are introduced into the slots 2l to extend between the reilector member and the casing so thatupon rotationl of the slneld member the tongues will pass luto the slots 21 and the lateral portions 19 and 22 of the respective slots and will interlock to permit the shield member to slide wholly behind the reflector.

1m It is not however desired. to i assume this position', as the shield will remain suiliciently lapped with relation to the reflector member as to facilitate its rof tative movement to cover the redectorllt) which can be readily accomplished by givtively simple lamp structure has been provided whereby the reflector can be covered at will to materially reduce the amount of light normally thrown out and. wherein the eiciency of 'the relector When it is desired to utilize tbefnll'beneiit thereoli is not impaired.

lfilhile we have illustrated and described a particular We have merely done so for the sake of' convenience and we do not wish to be limited to that particular embodin'aent as it is obvious that numerous changes may be made Within the details of construction thereof Without in any Way departing from the vspirit ci' the invention or exceeding the scope of the appended claims.

What we claim ie:- l l. ln a lane@E the combination with a casing, of e cup-shaped reflector held in the casing, a Cupehaped Shield member seated in the reflector member, said shield memher and reflector member being provided with reo-acting slotted portions whereby the shield member maybe rotated and having its major portion lie outwardly of the re- Hector member and-means for rotating the shield member.

embodiment of our invention7` mennen ln a lamp, the combination with a cupshaped reflector member having an opening in its base, a cup-shaped member seated in the reiector member, a lampcar-V rying sleeve carried by the guide member and extended through the opening of the shield, and said shield and reflector meinbers being provided with coacting slotted portions' whereby upon 'rotation of the shield member it may move to lie outwardly of the reflector member to expose the same.

3. In a lamp, the combination with a cupshaped refiector member having'a flange at its mouth and an opening in itsbase, of a cup-shaped shieldrinember Seated in the re'llector member and provided at-'its mouth with a flange bearing against the reflector flange, and a lamp carrying sleeve carried by the base ofthe shield and passed through the reflector base and said shield and reflector being provided with similarradial 'slots with the end portions of the slots of the respective members extended laterally opposite directions, whereby the shield member may move to have its major portion tp lie behind the reflector portion.

ln "testimony whereof, We aiiix our sig natures, in thepresence of two Witnesses. MAURUS J. QESTREICH. HENRY N. OESTREICH.
